WHEEL.

Application filed August 28, 1919, Serial No. 320,357.

To all whom it may conce/n.2

Be :it known that I, WILLIAM P. DAL- RYMPLE, a citizen of the UnitedStates, and a resident of Chicago,` in the .county of Cook and State ofIllinois, have invented certain new and useful Improvements in Wheels,of which the following is a specification, reference being had to theaccompanying drawings.

My invention relates to wheels and it has for its principal object theprovision of a new and improved form of wheel in which the hub isconnected to the rim by sheet metal plates and in which improved meansis employed for securing the rim in position and for producing thedesired tension upon the parts. it is another object of my invention toimprove the form and construction of wheels of this type in sundrydetails hereinafter pointed out. The preferred means by which l haveaccomplished my several objects are illustrated in the accompanyingdrawings and are hereinafter specifically described. That which lbelieve to be new and desire to cover by Letters Patent is set forth inthe claims.

the same reference characters,-2O indicates the inner hub of my improvedwheel pro vided with a cap 21 secured thereon by means of screw threadsserving to hold the outer hub 22 in position through the medium of adiagonally disposed flange 23 against which the cup 21 abuts, the twohub members having a diagonally disposed bearing upon each other at oneenol for insuring proper co-operation. ably mounted upon the outer hub22 upon which it is adapted to be adjusted by means of a screw threadedring 25 which abuts against the end of the hub 22. As will be readilyunderstood, the parts 22 and 24, together with the adjusting ring 25,comprise in effect an adjustable outer hub member. Sheet metal parts 26and 27, which in the construction shown are in the form of discs, areinterposed as hereinafter described between the outer hub member and therim 28. As is shown in Fig. 2, the rim 28 comprises, in the constructionshown, a collapsible flange part 29 engaging la suitable groove in oneedge of the part 28, for assisting in holding demountably in position, apneumatic tire 30 of any suitable type.

The sheet metal web portions 26 and 27 are, in the construction shown,secured to the outer hub member by means of annular flanges 31 whichengage tapered ring portions 32 forming parts of the outer hub member.Split rings are mounted within the anges 31 of the web portions, suchrings being tapered upon their outer faces to correspond to the interiortaper ofthe tapered ring portions 32, as is best shown at the bottom ofFig. 2. The rings 32 are adapted to be expanded for forcing the flanges31 into snug engagement with the rings 32 by means of screws 34 havingtapered heads 35 adapted to` abut against the beveled ends of the ring33, as is clearly shown in Fig. 3` the screws 34 being held in positionby supports upon the adjacent portions of the outer hub member. As willbe readily understood., when the split ring 33 has been once expandedserving to force the flange 31 of the web 26 into engagement with thetapered ring portion of the outer hub memloer, the web member is securedpermanently in position with respect to the outer hub member. beingincapable of being detached A sleeve 24 is slid-l therefrom upon thesubsequent collapsing of the split ring The connection of the sheetmetal parts 26 and 2l' with the rim 28 so as to make the rim easilydemountable in the construction shown, comprises interengaging hookswhich can be brought into and out of operative engagement as may bedesired. s is shown in Fig. 2, each of the sheet metal parts 26 and 27is provided at its outer periphery with an annular hook 36, such hooksengaging hooks 37 upon the inner face of the rim 28, the hooks 37 in theconstruction shown being formed integrally with'the rim. As is shown inFigs. 5 and 6, the rim 28 is eut out at one point so as to provide forthe collapsing of the rim. As will be readily understood. when the endsof the rim are drawn together serving to reduce the effective diameterof the circular rim 28. the annular hooks 36 can be moved into or out ofengagement with the hooks 37 of the rim, and the rim can be moved out ofposition on the wheel. lVhen, however. the rim 28 is again placed inposition and expanded by forcing the ends of the rim apart. theeffective diameter of the rim is increased. placing a tension upon thehooks 36 and 37 and upon the sheet metal parts 26 and 27.

My preferred means .for expanding the rim 2S comprises a suitable meansfor foreing the ends of the rim apart. ln Figs. 4lto 7 inclusive, I haveshown a wedge construction for accomplishing this result. A wedge 3S,beveled at its edges, as is best shown in Fig, 6, is inserted betweenthe ends of the rim 28 and driven in until the desired expansion of therim is secured. lSeats are preferably formed upon the end portions ofthe rim in diagonal position therein, as is shown in Fig. 5, by means oflugs 39 struck down from the material of the rim, the end portion ofeach of such lugs being beveled so as to hold the wedge 3S in position,as 'is best shown in Fig. 6. As is also shown in this figure, the seatsfor the wedge 3S are preferably reinforced by suitable welding asindicated at 410 in said vfiig. 6. rfhe wedge 38 is adapted to be vheldin position by means of havin its end portion il' forced into engagementwith the ffange 29, being further supported in this position by means ofa machine screw Ll2 having screw-threaded connection with the flange 29.

Referring to S and f) which show a modified form of means for expandingthe rim, 43 and 4.4 indicate pins journalled between the flanges of thehooks 37 of the rim 28, such pins being connected together b v means ofa double-acting screw t5 provided upon its central portion with a wormgear 46 which is operated by means of a worm 4J secured in position inany suitable manner.

lf?.eferring to Figs. l0 to le, each Of which shows a modified form ofstructure, it will be seen that in F ig. 10 a double hook 18 is employedupon the rim 28 in place of the two separate hooks of the constructionfirst described. In Fig. 11, the hooks 37 are formed upon a band 49secured to the rim 2S by means of rivets 50 instead of being formedintegrally with the rim as in the construction first described. In Fig.12 a single hook 51 is employed adapted to receive both of the hooks 36of the sheet metal discs 26 and 27. In Fig. 13 a single hook 52 isadapted to receive the hoolr 53 of a sheet metal web 5aof a heavierweight adapted by itself to stu port the hub with reference to the rim.In Fig. le' a piece of resilient material 55 is inserted between thehoolr 53 of the web and the hook 52 of the rim.

By the use of my improved construction, l have provided that any givenportion of the rim may have in effect a free inward sliding movementwith respect to the hub, whereby the hub may be supported bythe base 54or by either one of the plates 26, 2T, in concentric position withrespect to the upper portion of the rim, While at the same time thelower portion of the rim is permitted to give upwardly under theinfluence of the weight carried by the hub.

While l. have shown the rim in lf'igs. 13

an d lll; as being supported by the singleplate 5ftformed of' a singlesheet of metal, I desire to have it understood that l do not wish to berestricted to the formation of such single plate in integ al form from asingle sheet of metal, but that on the contrary, the term single plateis used in the specification and claims to designate a single supportingdisc structure, to distinguish from the double plato construction, asillustrated in the remaining figures in which two plates, 26 and 2T, areemployed in spaced relation to each other so as to give an effectivedouble support for the hub.

Se far as l am aware, l am the first in the art to provide for securinga wheel'rim in position about the hub by expanding the rim so as tobring cooperating hooked parts into operative engagement and my claimsare to be construed to cover this expedient broadly, whether in the formof wheel shown in the drawings or in any other form. lVhilef prefer tomount the rim demountably in position, it will be understood that l donot restrict myself to the use of that type of structure except in sofar as the claims are specifically limited to a construction of thatcharacter. I wish it also to be understood that in my use of the termrim in the specification and claims l do not limit myself at all to theform of rim shown in the drawings which directly supports the tire, butrather refer broadly to a band or equivalent part at the periphery ofthe wheel which ither by itself or in Connection with other parts yformsthe' member upon which the hub is supported by the spokes or equivalent`structure. While I have illustrated in some of the drawings the use oftwo plates or heads 26-27 supporting the hub with respect to the rim, Ido not desire `to be restricted to this construction except ashereinafter specifically claimed, inasmuch as it is evident from aninspection of F ig. 2 that each of the plates 26-27 acts entirelyindependently of the other plate. Since either plate could be removedentirely without affecting the arrangement 'or operation of the other,it is evident that either plate is adapted by itself by hookedengagement `with the rim to support the hub.
